Permissions around the Interactive Objects in your space are managed through assigned User Roles. Under the Object Authority Management table in Space Settings, you'll be able to set which User Roles may interact with each Object type.
Access the Object Authority Settings in the Space Settings Menu: Space Settings > Setting > Space in the Main Menu.
*Note: Remember to click on the Save button after making any changes from the settings page, located at the top right of the Space Setting page.
